Problems solved by technology

[0003] At present, there is little research on the temperature-resistant cigarette paper required for heat-not-burn. The domestic China Tobacco Modi (Jiangmen) Paper Co., Ltd. improves the temperature-resistant performance of cigarette paper through sizing and coating (patent publication number CN106480773A ), the sizing agent is a common sizing agent, and the preparation of the coated coating is complicated. The weight of the cigarette paper produced by this method is relatively high, generally greater than 50g / ㎡, which affects the machine adaptability of the cigarette paper and increases the cost of paper

Abstract

The invention belongs to the technical field of cigarette paper, and particularly relates to a method for improving the temperature resistance of cigarette paper. The method comprises adding glycerolin the production process of the cigarette paper. According to the invention, a 3-5 wt% glycerol aqueous solution as a sizing agent is applied to common cigarette paper, the phase change heat absorption property of glycerol is utilized to improve the temperature resistance of the cigarette paper, and compared with the cigarette paper without glycerol, the temperature resistance is improved by 15-25 DEG C.

Description

technical field [0001] The invention belongs to the technical field of cigarette paper, in particular to a method for improving the temperature resistance of cigarette paper. Background technique [0002] In recent years, with the strengthening of the public's awareness of the dangers of cigarettes and the strengthening of government regulations on cigarettes, the international traditional cigarette market has been gradually declining. At the same time, new tobacco products have grown rapidly against the trend. New tobacco products mainly refer to tobacco products that are different from traditional cigarettes, including new cigarettes, smokeless tobacco products and electronic cigarettes, which can not only meet the needs of smokers, greatly reduce the harm to the human body, but also produce Less or no smoke is produced, reducing hazards to the public and the environment. Among them, heat-not-burn cigarettes are currently the most rapidly developing new tobacco products w...
